it isn't. but it is a red herring as it doesn't have any thing to do with the question
if i don't know what i am talking about (i often don't BTW) then you or sammy have a chance to shut me up quick
take 10 seconds and explain what is happening with the wheels of the plane AS PER THE ACTUAL question.
sammy has tried the "they spin twice as fast" fail before, and we can forgive and forget that. let's start from scratch.
if you think the plane takes off, walk us through the whole wheel thing and you'll be a superstar…. imagine finally ending this thread!

Not a very good illustration of your point I'm afraid. Are you trying to imply that the force it takes to move the board forward in relation to the ground doesn't increase with the speed of the treadmill?
i.e. The arm strength it would require to hold your position on a treadmill moving 20mph would be the same as the arm strength required to hold your position on a treadmill moving 200mph? What happens when you reach the limit of your strength (limit of thrust on an airplane)

It's the same scenario, get it?
Here's my description of the plane on a conveyor:
1) Pilot throttles up, wheels overcome static friction and begin to rotate
2) Conveyor recognizes velocity of the wheels and begins to travel backward, with a linear velocity equal, but opposite to the linear velocity of the wheels themselves (when viewed with respect to the surrounding calm air)
3) Engine thrust overcomes both rolling friction and aerodynamic drag causing the plane accelerate down the runway, bringing with it the wheels which are now rotating with a tangential velocity of twice that of the linear velocity of the wheels themselves (when viewed with respect to the surrounding calm air)
4) Linear velocity of plane (and linear velocity of wheels given that they are bolted on) exceeds takeoff speed and lift forces from the wings overcome gravitational forces, allowing the plane to takeoff with its wheels rotating with tangential velocity at twice takeoff speed (when viewed with respect to the surrounding air.)
Whew, how's that sound?
and…..HANA PA'A!!! FISH ON!
Can you hear the reels screaming? Polls are bent, line is straining, but can
they keep this one on?
